CENTER-BEARING PLATE FOR CARS.

SPECF-ICATION forming part of Letters Patent No. 416,274, dated December 3, 188,

Application filed October 14, 1889. Serial No. 326,931. (No model.)

To'ctZZ whom t nca/y concern:

Be it known that I, CHARLES T. ScHoE'N, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Center- Bearing Plates for Railway-Cars, of which the following is a full, clear, and eXact description.

This invention relates tol center-bearing plates for railway-cars, and more particularly to that class of such articles manufactured of pressed steel or other wrought metal.

The object of the invention is to make a plate in which is a central bearing-to sust-ain the load, prevent crushing, and equalize the load when the cars are laterally inclined.

The invention consists in center-bearing plates in which the upper plate is made with a depending bearing and the lower plate is made with a rising bearing, having a seat for the depending bearing of the upper plate, and a rim projection above such seat to prevent the lateral escape of the upper' bearing, the bearings in both plates being returned to the base-line of the plates to afford crushing, and the plane of contact of the bearings of the two plates being parallel with the bases of said plates to prevent disturbance of the load when the oars are laterally inclined, substantially as hereinafter set forth and claim ed.

In the accompanying drawings,illustrating my invention,'in the several figures of which like parts are similarly designated, Figure 1 is a longitudinal section, and Fig. 2 is an end elevation. Figs. 3 and 4: are longitudinal sections of modifications.

The base a of the upper plate is made with longitudinal iianges I) to engage the car-body timbers, and it' is provided also with boltholes, as usual, and also studs, if desired, as in the center-bearing plates of my former inventions. The base is made vWith a cent-ral depression or depending bearing c, whose end may be fiat, as at d, and which is returned at e to the base-line of the base a, and there provided with a flange f parallel with the base. This iiange has the king-bolt hole g. The return of the depending bearing re-cnforces the plate and prevents crushing. The lower plate has a base 7i, with iianges t', boltholes, and studs, as needed, for engaging the timbers of the car-truck, and it is made with a central bearing j rising from it and having a Hat seat 7c to receive the depending bearing of the upper plate in a pla-ne parallel with the bases of the plates. The bearing j, moreover, is projected beyond the seat 7c to form a rim projection Z, surrounding the bearing c and circumscribing its lat-eral motion. The said bearing drops from the seat k by a return m and flange n to the base-line of the plate, and so re-enforces the lower plate.' The lian ge n is provided with the kin g-bolt hole 0, which is in alignment with the king-bolt hole g in the upper plate.

I prefer to make the surface d of the upper plate-bearing and the seat 71; of the lower plate-beari ng iiat, for I have found that where the contactfsurfaces 0f the bearing-plates are curvilinear there is a tendency to shift the load in rounding curves, and this difculty is overcome with the construction mentioned. There is enough space between the bearing c and the rim Z to permit all necessary play of the plates one upon another without the plates getting outof center.

The plates and their returned central bearings are integral, by preference, and may be struck up in dies or pressed from steel plate, or the-y may be otherwise manufactured. The bearings may be made separate wholly or in part and attached to the structure, and this is especially true of the smaller-size plates, as indicated in Figs. 3 and et, wherein in Fig. 3 there is no return and in Fig. 4 the bearing is separate.

Vhile I prefer the construction and arrangement of parts shown, yet it is within my invention to reverse these parts and make the upper pla-te as the lower'one is shown, and vice versa.

That I claim isl. Center-bearing plates of wrought metal provided with integral bearings having flat contact-surfaces, and a rim projection from one of the plates surrounding or circumscribing the bearing from the other, substantially as described.
